Specification of Letters Patent.

Patented Feb. 16, 1315.

Application filed October 23, 1913. Serial No. 796,900.

To all whom it may concern Be it known that 1, JAMES M. BREsnn, a citizen of the United States, residing at Mattoon, in the county of Goles and State of Illinois, have invented certain new and useful Improvements in Road-Machines, of which the following is a specification.

This invention relates to improvements in road machines, and has for its object to rovide an improved form of road machine of the type shown and described in my copending application 764,777.

In a machine of the class described, I find it desirable at times to use another form of means for positively spreading the scraping members and securing them in adjusted relation to the body.

Another object is to provide, in a machine of the class described, having extensible bars, means to maintain in spread relation, said scrapers. Where said bars also provide a fulcrum or derrick for the raising and lowering of said scrapers, I also provide means for reducing the friction thereof and insuring meshing of the gearing, as will be more fully described. I

Other objects will be set forth and made apparent in the following specification and accompanying drawings, in which- Figure 1 is a plan view of my improved machine. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation of the same. Fig. 4 is a detail partially in section of a shaft locking means. Fig. 5 is a plan view of the same showing extensible bars with the racks and pinions. Fig. 6 is a detail of my spreader bar construction. Fig. 7 is a plan view of the same. Fig. 8 is a par tial perspective of the same. Fig. 9 is a partial detail view of an extensible bar guiding means. Fig. 10 is a side elevation of the same.

Like numerals refer to like elements throughout the drawings, in which- 10 indicates generally the body of my machine having the longitudinal beams 11 rigidly secured together by a cross beam 12 at the front thereof and the structure generally indicated by numeral 13 at the rear portion thereof, this structure being similar in my co-pending application and not requiring an amplified description herein. Scraper bars 14: are located'outwardly of the body and pivotally attached adjacent their rear extremities to the cross beam 15 carrying a pulley 16 over which travels the cable or rope 17 secured at one extremity to an eye-bolt 18 and passing over pulley 19 to the winding drum 20 operable by the hand wheel 21. The cable 17 may be used to raise or lower the rear portion of the scrapers 14: through the medium of the beam 15 as will be apparent.

Uprights 22 extend upwardly from and are secured to the beams 11 and carry the spaced apart bracket arms 22 at their upper portion journaled in and extending between which are the shafts 23 upon which are car ried the winding drums 2 1 operable by the hand wheels 25 for a purpose to be hereinafter described.

A transverse guiding member 26 is located above the body 10 and extends across and is secured to the uprights 22 projecting at either side some distance beyond the body 10, as will be apparent in Fig. 3. This guide member is shown in detail in Fig. 1 and comprises the channel 26 having the upwardly extending flanges 26". At its extremities are located the rollers 27 rotatably mounted in brackets 28 carried at the under side of said beam 26. At its central portion is locatedthe inverted channel section 29 forming a short closed passage as clearly shown in Fig. 5. This is secured to the lower channel 26 by the side plates 30 and the shaft 31 extends through both said chambers and is journaled therein as clearly shown.

Extensible bars 32 are slidably mounted in the guide member 26, said extensible bars being preferably two in number and spaced apart as shown in the drawings. These bars 32 comprise I-beams in one channel on which are located the racks 33 adapted to cooperate with the pinion 34 mounted on shaft 31. It will be apparent that rotation of the shaft 31 will operate to move the bars 32 in opposite directions.

An upright roller 35 is located adjacent each end of the guide beam 26,being held 1n place thereon by the arm 35 and pin 35 as shown in Fig. 9. This roller coacts with the flanges 32*, the same being of suflicient size to prevent contact of the teeth of the corresponding rack 33. This roller 35 is spaced from one flange 26 of the guide member 26 a sufficient distance to permit sliding of the corresponding bar 32 therebetween, but also so as to insure a fairly snug fit thereof. One of these rollers 35 coacts with each of the extensible bars, the rollers being oppositely disposed with respect to the longitudinal axis of the guide members 26, as will be apparent. The rollers 27 serve to support the weight of the corresponding bars 32 and thereby decrease the friction between them and the guide member 26.

Two pairs of rollers 40 are mounted upon the axles 41 adjacent the center of the beam 26, as clearly shown in Fig. 4, serving to receive the upward thrust of the extensible bars. It will be apparent that when it is desired to extend or draw in thebars 32 rotation of the hand wheel 31 carried by shaft 81 will accomplish such purpose.

A ratchet oi notched wheel 42 is also mounted upon the shaft 31 above the channel 29 and serves for a locking means as will be described hereinafter. A short arm 43 extends outwardly from one side of the plate and pivotally mounted therein is the detent or latch 44 having its extremity 44 adapted to fit in notches of the ratchet 42 when in the position shown in Fig. 4.

A rod 45v is pivotally attached at 44* to the opposite extremity of the detent or latch 44 at one extremity and is pivotally attached at its other extremity 45 to a foot lever 46 having the flattened foot portion 46 at one extremity and pivoted at its 30 jother extremity at 46". It will be apparent that depressions of the lever 46 will release the. ratchet 42 and permit the extensible "bars to be extended or drawn in with respect to the body of the machine.

Pulleys 48 are mounted at the outer ends of each of the extensible bars 32 and a rope or cable passes thereover from around pulleys 49 carried by the scrapers 14, the cables 47 being secured at one extremity lto the eyes or shackles 50 in the lower side of the extensible bars 32. These cables 47 extend to their respective winding drums 24 operated by hand wheels 25. p

In the operation of this device when it ,is desiredjto widen the scrapers, the same may be let down into contact with the road and the stress resulting from contact of these scrapers with the road will operate to draw the former apart to the desired po- ,sition, the extensible bars 32 either being permitted to travel therewith, or the drums 24 being permitted to allow unwinding of the cables 47 or both.

1 To maintain the scrapers firmly in scraping position when so spread apart, I

provide what I term spreader bars curved outwardly and downwardly from the body of the machine and bent backwardly, as indicated at 60*, being pivotally secured at 60 their outer extremities 60 by pins 61 or the like to the scraper bars 14. These spreader bars extend upwardly over the beams 11 of the body 10, being straightened along a portion of their length to lie approximately parallel to the plane of the body. The beams 11 are slotted or grooved as indicated at 11 in Fig. 6, the slots being of suflicient size to permit play of the'bars therein to provide for the raising or lower ing of the scraper bars 14.

Thespreader bars 60 are provided with the notches or grooves 60 along" their straightening portion and a pivoted latch or detent 62 pivoted at one extremity to the corresponding beams 11 by means of a pin 65 extending through an offset supporting strip 66 on the beam 11 are adapted to drop into the corresponding notches 60 to lock said bars 60 against movement with respect thereto, as is clearly shown in- Figs. 6, 7 and 8. When it is desired to spread the scrapers apart or draw them'in the latches or detents 62 are dropped out of engaging position, shown in full lines in Fig. 8, backward until they rest upon the supporting strips 66 whereupon the'spreader bars 60 are free to move laterally with respect to the supporting beamsll so that movement ,of the extensible bars 32 or action of the rod to spread the scrapers apart'will not be ofiset by the engagement of the latches with the bars 60.

The notches 60 in the spreader bars 60 2 have a width greater than the thickness of the latch or detent 62 in order to permit the horizontal angular movement of the scraper bars between the positions shown in full and dotted lines in Fig. 1.

- For convenience in operation and construction, I locate the spreader bars 60 adjacent the uprights 21 so that the operating wheels 25 and 31%, together with the engaging points ofthe spreaders 60, are located closely adjacent each other soas to enable 1. In a device of the class described, a
